Types of nonuniform structures, boundary electron states, and chiral anomaly in semiconductors with Dirac bands
Pankratov O. A.
All types of nonuniform semiconductor structures are classified on the basis of an effective Dirac Hamiltonian. For one version—an antiferromagnetic domain wall—there is an analogy with the chiral anomaly, manifested as the presence of a magnetic moment perpendicular to the plane of the wall.
